Although solid details in regards to Seth Rollins' knee injury are still being kept quiet, WWE has pulled him off of this weekend's live events.
WWE issued the following statement about Rollins' status this morning:
"The full extent of Seth Rollins' injury remains unknown, but WWE.com can confirm that the former WWE Champion has not been cleared to compete at WWE Live Events this weekend. A full medical update will be given this Monday night on Raw."
Rollins was injured on Monday Night Raw, when an attack by Samoa Joe led to his knee buckling. Rollins could be overheard saying "I hope so" when Joe asked if he was okay. Rollins was tentatively planned to face Triple H at WrestleMania 33 after missing last year's WrestleMania with a torn ACL on the same knee.
